Abstract: A METHOD OF AND APPARATUS FOR FORMING A POLYMERIC SHEET STRUCTURE HAVING COMPARATIVELY HIGH DENSITY SKIN   LAYERS AND A COMPARATIVELY LOW DENSITY CORE LAYER            Abstract In a method and apparatus for producing a foamed polymeric sheet having comparatively high density skin layers and a comparatively low density core layer, molten polymer containing a foaming agent is extruded from a die 18 into a post-extrusion region 22 defined by the die 18 and a spaced pair of rotating chill rolls 24 which are spaced from the die 18.  The post-extrusion region 22 is maintained at a pressure sufficient to at least inhibit expansion of the foaming agent through the use of cooled sealing elements 26 which occupy a substantial portion of the space between the die 18 and the chill rolls 24, and are spaced from the chill rolls 24.  The rolls 24 and the sealing elements 26 are cooled so that molten polymer in the space between the sealing elements and the rolls becomes solidified, completing the seal.  The chill rolls 24 are maintained at a temperature below the temperature of the molten polymer to aid the skin formation on the surfaces of the polymer.  If desired, the polymer can pass directly from the chill rolls into a water bath.

Abstract: Abstract of the Disclosure A method of feeding cement into a drill hole for cement bolting of a rock, according to which a feeder pipe (2) is pushed into the hole essentially to the bottom of the hole portion to be filled with cement, cement is fed into the hole beginning from the bottom of the hole portion, and the pipe is displaced outwards in the hole when the cement fills the hole. The feeding of cement is stopped and the pipe is removed when the amount of cement is sufficient to fill the gap between the wall of the hole and the rock bolt to be pushed into the hole. The displacement of the pipe is controlled by means of the filling pressure (TP) caused by the cement fed between the pipe tip and the bottom of the hole portion to ensure that the hole is reliably filled despite possible cracks and crushed zones.       An apparatus for carrying out the method comprises a feeder pipe provided with a tip of such a size that the penetration of cement through the gap between the hole and the tip requires a pressure which is higher than a predetermined set value of the cement feed pressure and causes an outwards pushing force on the tip.

Abstract: ABSTRACT:          "Decoder for the decoding of code words which are protected against the occurrence of a plurality of symbol errors by means of a Reed-Solomon code. and reading device for op-tically readable record carriers which comprises such a decoder".       A description is given of a decoding system for code words which are protected against the occurrence of a plurality of symbol errors within a code word by means of a Reed-Solomon code. After each formation of the syndrome symbols, the key equation is solved, assuming an as small as possible number of symbol errors. When a plausible number L is found using 2L syndrome symbols, an additional number of further syndrome symbols is considered for determining the discrepancy quantity. The locator equation is directly solved when it is of a low order; in the case of a higher order, a Chien search cycle is performed and each time a symbol error is found it is removed by division until the order becomes low enough for direct solution. The decoding system is suitable for implementation by means of a microcomputer and for use in a reading device for optically readable record carriers.

Abstract: ABSTRACT          Improvements Relating to Road Planing Equipment The invention provides road planing equipment.   A beam which lies substantially horizontally in relation to the ground carries a cutting unit for movement thereon. As the cutting unit moves along the beam, it planes the road surface to a controlled depth.   The beam is supported at one end by a bracket which can move a frame transversely of the beam to move the beam laterally.    The frame is supported on spaced, extensible and contractible legs.   At the other end the beam is supported on a single expansible and contractible leg.  Thus, the height of the beam above the ground and the angle of the beam in relation to the ground can be adjusted.   The beam can be pivoted to an upwardly directed out of use position.

Abstract: IMPROVED CONVEYOR SYSTEM FOR A SHEAR DISCHARGE           Abstract of the Disclosure A shear discharge conveying system including a plurality of individual conveying belt modules connected to a main frame for easy repair and replacement.  Impact bar assemblies are spaced between the modules to prevent sheared material from impacting directly on the belts.  Rows of vertically extending and retracting gauging supports are adjustable to match the cut size, and tension links connected between the rows prevent the material from nosing down between supports.  A scrap gripping and conveying mechanism moves strips of scrap transversely to the conveying direction directly behind the shear before the strips can contact and foul the conveyor.  The main frame is mounted on air pads so a single operator can move the entire system to and from the shear.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention refers to a reluctance motor with windings for one or more phases, and arranged - for each phase - around two or more poles.  The stator surrounds a rotor incorporating two or more rotor poles.  The invention is characterized in that the motor is of the commutator type with a rotor position indicator, together with the fact that the stator poles branch into teeth.  In this connection, it is expedient for each stator pole to have a winding and to be branched into two or three teeth.  With this arrangement, the motor is capable of a low speed and high torque, despite having a low number of winding coils, and thus the manufacturing cost is low.

Abstract: A B S T R A C T      A hollow body, a rotor, with holes in the bottom and the side wall, is immersed in a liquid and caused to rotate by a shaft suspended over the liquid.      The liquid, entering the rotor through a hole in the bottom, acquires a surface of a paraboloid of revolution by centripetal force.   The centripetal force throws liquid out through holes in the side wall, whilst new liquid continuously enters through the bottom of the rotor.      The shaft for the rotor can be hollow, and gas, solids or liquid materials can be added to the liquid through it.      The disclosure allows the treatment of different types of liquid, from aqueous suspensions to molten metal in various ways.

Abstract: VARIABLE POWER LENS SYSTEMS   ABSTRACT    There has been provided a variable lens.  In one form the lens power may be varied and in another the power may be selectively fixed in a carrier material.  There are no moving mechanical parts but instead an optically active molecular material such as liquid crystals.  In one embodiment, the lens and control means for varying the power of the lens are mounted on a common substrate.  The lens may be a single optical element or a multi-element device such as a Fresnel lens.  A variable gradient index of refraction is achievable by applying a controlled stimulus field to the lens.  For example, a geometrically configured matrix of electrical voltages, each at a selected addressable location relative to the optically active material, provides the gradient in one embodiment.  A thin film embodiment finds applications in magnifying glasses, cameras, telescopes, microscopes, as well as for intraocular and contact lenses for the human eye.
